Re: Xbox One
The Xbox One Might Be Out On November 8th (pic)
The PlayStation 4 is out in the US on November 15. The Xbox One? Well, it's looking like it could hit the market a week ahead of its competitor.P
While Microsoft is yet to officially announce the big day, and "release dates" on retailer sites are usually little more than window dressing, we've heard from someone a little closer to the launch that Microsoft is planning a November 8 release for its latest console.P
The source, who works for a marketing company that handles signage and product placement for retail giant Walmart, passed along what they say is an email for a company conference call that lists all the midnight openings the chain has planned.P
As you can see, alongside the big holiday games, and just before the PS4, is the Xbox One, at November 8. Note however that, unlike every other date listed, the Xbox One's lacks a "confirmed" status, suggesting Microsoft is yet to lock the date down.
The fact it's not locked down of course means the day could change, but it also suggests it's a recent decision. Almost as though Microsoft were waiting for Sony to commit to a day before scheduling their own launch, in order to get the jump on the PS4...

Re: Xbox One
Nice, wouldn't have thought the eSRAM to be directly accessed by the CPU. Looks like I was wrong about that. (Although, the arrow between the eSRAM and the CPU is not a thick arrow like all of the data transfer arrows and I haven't been able to find what it means.)
Still, I don't think it fits under AMD's HSA specifications for hUMA, it looks like the GPU cache still needs to be flushed in the Xbox One. There's also nothing I see in the specs that suggests the memory has uniform access as per the hUMA spec, without that its just unified memory (which is what the 360 already has), big difference in performance there.
A lot of what they presented actually just confirmed what people were speculating regarding the actual numbers (768 Shaders, 48 Texture units, 16 ROPS, 2 ACE processors).
My main issue with the presentation is that they are still trying to spout out what is clearly bullsh!t regarding the 109 GB/s minimum and 204 GB/s peak bandwidth (something that Anandtech, ArsTechnica and TechPowerUp all agree is likely BS). I want to know which orifice these numbers were pulled out of.Comment

Re: Xbox One
I doubt it but if they do pull it off all I can say is... wow.
You're the tech guy so which one is it, clearly or likely?
Because each word heads in a different direction.
I honesty still don't even know what that post with the pics means, nor your breakdown of those numbers.Comment

Re: Xbox One
I'll just put the exact quotes from them, should have done it last time, sorry.
Anandtech:
"According to their data, there’s roughly 50GB/s of bandwidth in each direction to the SoC’s embedded SRAM (102GB/s total bandwidth). The combination of the two plus the CPU-GPU connection at 30GB/s is how Microsoft arrives at its 200GB/s bandwidth figure, although in reality that’s not how any of this works. "
Ars Technica:
"Similarly, the company claimed that there was more than 200GB of bandwidth within the system. Again, the number had no context or clarification and if rumors are to be believed, it suggests some rather creative accounting: 68 GB main memory bandwidth, 102GB bandwidth to an embedded SRAM buffer for the GPU, and 30GB bandwidth between the CPU and GPU. While that does add up to 200GB, there are no two parts of the SoC that can communicate with each other at 200 GB/s."
TechPowerUp:
"Xbox One chip is a slightly different beast. It uses the same eight "Jaguar" 1.60 GHz cores, but a slightly smaller Radeon GPU that packs 768 stream processors, and a quad-channel DDR3-2133 MHz memory interface, which offers a memory bandwidth of 68.3 GB/s, and holding 8 GB of memory. Memory between the two subsystems are shared in a similar way to PlayStation 4, with one small difference. Xbox One chip uses a large 32 MB SRAM cache, which operates at 102 GB/s, but at infinitesimally lower latency than GDDR5. This cache cushions data-transfers for the GPU. Microsoft engineers are spinning this off as "200 GB/s of memory bandwidth," by somehow clubbing bandwidths of the various memory types in the system."
But the reason why everyone is confused about Microsoft's numbers is because they said that they recently discovered a way to read/write onto the eSRAM at the same time. That should theoretically double the bandwidth, not just increase it by an arbitrary amount.
I mean, MS confirmed today that it's 4 x 256bit read/write on the eSRAM. 4 x 256bit x 853mhz = 873,472 Gbit/s = 109,184 GB/s; so the theoretical maximum should be double this (218GB/s). No one knows how Microsoft arrived at the 204 GB/s number. Are they just adding up all the bandwidth in the system? Is the eSRAM truly capable simultaneous read/write? It's just kind of weird that the theoretical maximum isn't 218GB/s and I just want to hear an explanation of how they arrived at the number.Last edited by Trapper700; 08-27-2013, 03:57 AM.Comment

Re: Xbox One
Trapper word is MS left some stuff out (for various reasons) and because they have a NDA with both AMD & Intel until Sept. 29th. Once the NDA is lifted we will get more information. I'm not a tech guy, but from the sites I've visited what was presented was some very interesting information, especially the eSRAM info you mentioned.
Here's a more clearer version of the info slide

Re: Xbox One
Mind sharing a link as to the NDA regarding MS and AMD/Intel? Or at least the date on which it's lifted? I couldn't find a source on that online, but I figured it would be something similar. I would have thought the NDA would lift when the consoles are released and no sooner.Comment

Re: Xbox One
I don't have a link, but the NDA info is coming from an "Insider"
Insider: There not going to go into 100% detail at hotchips.. go back to the wired picks mistercteam. See the diagram gpu core and cpu core that are labelled on the motherboard .. that is the other gpu and cpu? As these photos are of older x1 dev kit they were not available.. w2w will merge these chips buy wafer 2 wafer and incorparte the oban.... But as of right now ms are split in to three categories or level control... that seems to be the reason why there is no real pr to specify the detail. And so many problems have happen.. But a lot of the fanboy's do not understand. Sony has a contract in place with AMD that specified that they would have total control over the hardware public relations aspect. Which runs out on 29 September 2013 up intill this date Microsoft is not allowed to go public. It is in the license agreement with Intel as well. Sony had a 6-7 month exclusive hardware agreement basically. First in best served. This has not effected nintendo as they using different cpus.. And this sort of thing happens all the time in the pc cpu and gpu markets.. .. sad but true.
Up until now Microsoft had not had contractual agreements to modify x86-64 architecture or manufacturing agreements with intel.. Amd is the only other company to be allowed to manufacture and modify x86 x64 cpus. And Mark cerny had decided to pursue AMD for Sony and obtained licences agreements why back in 2010. And Sony could obtain agreements with Amd early only if they did not modify the x86 cores.. hence the of the shelf nature and all most tablet simplicity of the cpu gpu is another story.. The disrupt is Microsoft could not fab the chip ether, due to its ultra custom design. So this three billion that is floating around the internet. 3 billion is a small price to pay for any large corporate body specially when it has the contractual agreement that allows the corporate body to modify the chips for the next 100+ years. And the upside is Amd even agreed to fab them as well..
Can't say how valid the source is, but this isn't the 1st time said source claimed thisComment
